摘　　要：合成了3个含羧甲磺酰基蒽醌染料和相关中间体，并用热重法测出了染料及中间体的脱羧温度．结果表明，将羧甲磷酰基间接地连在苯环上可以降低脱羧温度．Three anthraquinone dyes containing carboxymethylsulfonyl group and relative in-termediates were synthesized. Thermogravimetry was applied to determine the decarboxyla-tion temperatures of the dyes and intermediates. The results show that decarboxylation tem-peratures decreased when carboxymethylsulfonyl groups connected indirectly with benzenering.
